Component mounter

1. A component mounter comprising:

a component transfer device configured to detachably hold a held nozzle tool to which a suction nozzle is attached, move the nozzle tool, and transfer an electronic component held by the suction nozzle to a mounting position on a circuit board;

a tool station configured to store an exchange-use nozzle tool; and

a control device configured to control operation of the component transfer device and perform mounting processing of the electronic component and exchange processing of the held nozzle tool, wherein

the component transfer device is provided with a head main body, and a tool holding device configured to hold the held nozzle tool and provided to be raisable and lowerable with respect to the head main body and rotatable around a rotation axis line,

the tool station is configured to be able to store the exchange-use nozzle tool at multiple different storage angles, and

the control device is provided with an angle acquiring section configured to acquire a storage angle of the exchange-use nozzle tool in the tool station, and an exchange control section configured to, during the exchange processing, raise and lower the tool holding device to remove the exchange-use nozzle tool stored in the tool station and to hold the exchange-use nozzle tool on the tool holding device, and configured to rotate the tool holding device based on the storage angle of the exchange-use nozzle tool to perform angle alignment of the exchange-use nozzle tool with respect to the head main body.

2. The component mounter according to claim 1 , further comprising:

an angle determining mechanism configured to allow raising and lowering of the exchange-use nozzle tool stored in the tool station and to regulate rotation of the exchange-use nozzle tool with respect to the tool station around the rotation axis line,

wherein the angle determining mechanism allows the exchange-use nozzle tool to be stored in the tool station at multiple types of storage angles that are predetermined.

3. The component mounter according to claim 2 , wherein

the angle determining mechanism is provided with

multiple hole sections provided on one of the tool station and the exchange-use nozzle tool at different positions around the rotation axis line of the exchange-use nozzle tool stored in the tool station, and

a pin section provided on the other of the tool station and the exchange-use nozzle tool configured to be inserted into the multiple holes sections,

wherein the rotation of the exchange-use nozzle tool around the rotation axis line is regulated with respect to the tool station at a storage angle corresponding to a positional relationship between the hole sections and the pin section by the pin section being selectively inserted into any of the multiple hole sections.

4. The component mounter according to claim 2 , wherein

the exchange control section, during the exchange processing, controls operation of the tool holding device to store the held nozzle tool in the tool holding device, from among the multiple types of the storage angles, at a storage angle at which a difference between the storage angle and the holding angle of the held nozzle tool angularly aligned with the head main body is minimized.

5. The component mounter according to claim 1 , wherein

the control device, during the mounting processing of the electronic component, controls the position of the suction nozzle based on an image of the board captured by a board camera provided on the component transfer device, and

the angle acquiring device is configured to acquire the storage angle of the exchange-use nozzle tool based on an image of the exchange-use nozzle tool captured by the board camera, an imaging target of the board camera being the exchange-use nozzle tool stored in the tool station.

6. The component mounter according to claim 5 , wherein

the angle acquiring section is configured to acquire the storage angle of the exchange-use nozzle tool based on a position of a mark provided on an upper surface of the exchange-use nozzle tool shown in the image of the exchange-use nozzle tool,

wherein the mark has information including an identification number and type of the exchange-use nozzle tool, the mark being an information code used in identification processing of the exchange-use nozzle tool.
